i get this error messages in my application:

query error:  ERROR:  duplicate key violates unique constraint "pg_type_typname_nsp_index"

failed query:  SELECT packv_uid INTO TEMPORARY my_new_to1c FROM new_to1c
connection error:  no connection to the server

it's my code:
for (;;) {
  doquery("begin work");
  doquery("SELECT packv_uid INTO TEMPORARY my_new_to1c FROM new_to1c");
  ....
  doquery("DROP TABLE my_new_to1c");
  doquery("commit");
  sleep(1);
}
new_to1c is view
may be it's related with

What language are you using to execute your code?  Maybe it has the same
problem that pl/pgsql does with caching temp tables?  It would be
created the first time it looped through your code, the 2nd time it
would crash trying to create the table again.

i think i understood:
 - after SELECT INTO, but before DROP TABLE i get error from some sql
command
 - transation is aborted and any commands (include DROP TABLE) are
ignored
 - after commit temporary table exist and on next loop i get error on
SELECT INTO
